From: weldat on 26 Mar 2010 05:38 Hi every body; i am working on xilinx EDK with MicroBlaze soft core processor. i am using Virtex 5 ML506 platform studio and my EDK is EDK 9.2 on this processor i am downloading C code for Elliptic curve diffie-hellman key exchange and it is done but result is not displayed on the hyperterminal so is there any body who can help me how to fix my problem? but the connetion of the RS232_uart is working properly i have checked it with simple C code. the baud rate is all ok thank you in advance. kind regards weldat --------------------------------------- Posted through http://www.FPGARelated.com

Try a decent terminal emulator first to eliminate that source of problem. Many people (including me) like Tera Term Pro, but there are hundreds of alternatives.

It turned out hyperterminal wasn't treating the hex '00 values as data despite the attempts to make the transfer "binary" and gummed up the whole effort. If you're using raw data, perhaps you should change to where you transfer ASCII hex characters instead. In pseudocode: 4'h0 == 8'c"0", 4'hf == 8'c"F"

Short pins 2 & 3 on the plug to see if characters get echoed when typing. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico(a)nctdevpuntnl (punt=.) --------------------------------------------------------------
